addComponent() [2/2]

void addComponent	(	const NormalDistributionBasePtr &	gaussian,
		float	weight )

addComponents()

void addComponents ( const GaussianMixtureDistributionBasePtr & other, const ::Ice::Current & c = Ice::emptyCurrent )

override

Multiply weight of each GM component with a given constant.

Parameters
